Honestly, this is the best motivation to buy everything there is, so that Dude can finally have a proper home, and to put a cherry on top. Add a small buff after achieving it, like an additional 5% to crafting or maybe a new item crafting/buying added, or allow dude to auto-leave a cold Juice in the fridge in exchange for Brew every so often.
I wouldn't mind other characters to join in, but for now Dude is the best candidate.
